Configuring Network Access
This chapter describes how to configure network access. The ACE appliance has four physical Ethernet
interface ports. All VLANs are allocated to the physical ports. After the VLANs are assigned, you can
configure the corresponding VLAN interfaces as either routed or bridged for use. When you configure
an IP address on an interface, the ACE appliance automatically makes it a routed mode interface.
Similarly, when you configure a bridge group on an interface VLAN, the ACE appliance automatically
makes it a bridged interface. Then, you associate a bridge-group virtual interface (BVI) with the bridge
group.
The ACE appliance also supports shared VLANs; multiple interfaces in different contexts on the same
VLAN within the same subnet. Only routed interfaces can share VLANs. Note that there is no routing
across contexts even when shared VLANs are configured.
In routed mode, the ACE is considered a router hop in the network. In the Admin or user contexts, the
ACE supports static routes only. The ACE supports up to eight equal cost routes for load balancing.
Note When you use the ACE CLI to configure named objects (such as a real server, virtual server, parameter
map, class map, health probe, and so on), consider that the Device Manager (DM) supports object names
with an alphanumeric string of 1 to 64 characters, which can include the following special characters:
underscore (_), hyphen (-), dot (.), and asterisk (*). Spaces are not allowed.
If you use the ACE CLI to configure a named object with special characters that the DM does not
support, you may not be able to configure the ACE using DM.
